Specification of Letters Patent.

Patented Feb. a, 1910.

Application filed June 28, 1909. Serial No. 504,849.

To all whom it may concern:

Be it known that I, NEWTON S. DAVIS, citizen of the United States, residing at Montrose, in the county of. Montrose and State of Colorado, have invented new and useful Improvements in Culverts, of which the following is a specification.

My invention pertains to sectional culverts such as are designed especially to be made of cement or analogous material; and it consists in the peculiar and advantageous construction hereinafter described and definitely claimed.

In the drawings accompanying and forming part of this specification: Figure 1 is a perspective view of one end portion of a culvert constructed in accordance with my invention. Fig. 2 is a plan view of the culvert.

Similar letters designate corresponding parts in both views of the drawings, referring to which:

A is the base of the culvert which is preferably molded or otherwise formed of cement or analogous material, and is made up of sections arranged end to end, or continuous, in the discretion of the parties practicing my invention. The said base is provided adjacent its longitudinal edges with upstanding lugs a, and part of its upperv side is inclined downwardly to its longitudinal center, as indicated by I), and clearly shown in Fig. 1.

The remainder of the upper side of the base2'. 6., the portions of said side between the lugs a and the inclined portions 1) are horizontal. This is materially advantageous because it permits of the segmental sections bein readily placed on the said horizontal portions of the base against the inner sides of the lugs a, and also because it permits of the segmental sections being so placed while their upper edges are separated by a considerable space. From this it follows that the filler C may be conveniently placed in the said space, after which the segmental sections may be permitted to move downwardly and inwardly until their lower edges rest solidly on the said horizontal portions of the upper side of the base A and their up per edges bear against opposite sides of the .filler C to securely hold the same in position.

In addition to the base A, my novel culvert comprises segmental sections B which are also, by preference, molded or otherwise formed of cement or like material, and a filler C, of lead or hard wood or other material consonant with the purpose of the filler, interposed between the upper and opposed longitudinal edges of the said segmental sections B.

I contemplate in practice making the base A and the segmental sections B in short lengths, this inorder that the lengths may be made at any convenient point and hauled or shipped to the point of use where two men can conveniently handle the lengths. I also in constructing the culvert lay the base A in a trench, and start with a length I), about half as long as the other lengths 6 Fig. 2, this in order to break joints between the segmental sections after the manner clearly shown in Fig. 2 and position the joints between the lengths at one side of the longitudinal median line of the culvert out of alinement with the joints'between the lengths at the opposite side of said median line. By reason of this relative arrangement of the lengths, there is no likelihood of the culvert being thrown out of line in case it tends to settle, and consequently no liability of the filler, hereinafter'described in detail, being weakened, displaced or otherwise affected. It will also be understood that the lugs a .will prevent spreading of the segmental sections B and B both before and after earth is tamped upon the same.

The filler C, of sheet-lead or hard wood or equivalent material, serves to compensate for any jar that takes place when a wheel of a vehicle strikes the side of the arch, or, in other words, prevents such jar from damaging the segmental sections forming the arch portions of the culvert. This will be appreciated as an important advantage when it is remembered that it is frequently necessary to carry culverts across roads.

It will be gathered from the foregoing that the sections entering into my novel culvert are adapted to be quickly and easily produced and as readily arranged in proper manner to form the culvert, and this without the employment of skilled labor.

The specific construction herein illustrated and described constitutes the best practical embodiment of my invention that I have as yet devised, but it is obvious that in the future practice of the invention such changes in the form, construction and relative arrangement of parts may be made as do not involve departure from the scope of my invention as defined in my appended claim.

Having described my invention, what I claim and desire to secure by Letters-Patent, 1s:

The herein described culvert consisting essentially of a base having upstanding longitudinal lugs adjacent its longitudinal edges and also having inclined portions 12 at its upper side extending upward from its longitudinal center, and horizontal portions intermediate the said longitudinal lugs and the outer longitudinal edges of the inclined portions 6, segmental sections arranged opposite each other on the base and between the longitudinal lugs thereof and having horizontal lower edges bearing throughout their width on the horizontal portions at-the upper side of the base and at the inner sides of the said longitudinal lugs; each of the said segmental sections being disposed at one side of the longitudinal median-line of eaaeoe the culvert and including a plurality of lengths, and the inner edges of the sections being vertical, andthe joints between the lengths of the section at one side of said longitudinal median line being arranged out of alinement with the joints between the lengths of the section at the opposite side of said line, and filler means interposed between the opposed vertical edges of the segmental sections and occupying the longitudinal center of the culvert and also interposed between the opposed vertical edges of the lengths in each segmental section.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
